PVC Heat Stabilizer

About PVC Heat Stabilizer

PVC heat stabilizer,the reason why use it in formulation is that the decomposition and plasticization temperature of pure PVC resin are very close. When it is heated to 130 - 140 , decomposition will occur and hydrogen chloride will be released. Therefore, it is impossible to process and manufacture plastic products with pure PVC resin. Additives are indispensable raw materials in the production of PVC plastics, which are determined by the inherent characteristics of PVC resin. Various additives must be added to improve the performance of PVC, so as to obtain various products with different performance and wide use. Therefore, PVC formula design is the premise and important process of PVC products processing.The PVC heat stabilizer is the most important additive in the formulation to keep the process smoothly,it include range of chemicals like Stearic acid salt,hydrotalcite.PVC heat stabilizers are classified as follows: Lead salt composite stabilizer,OBS organic base stabilizer,Organotin stabilizers,Liquid compound stabilizer,Calcium zinc composite stabilizer,Barium zinc composite stabilizer,Potassium zinc composite stabilizer.
